8-bit MCUs with extremely low standby power consumption

Ideally suited as watchdog and for motor or lighting controls:

Milton Keynes (UK), February 1, 2010 – The new 8-bit-microcontrollers 78K0/FY2-L, 78K0/FA2-L and 78K0/FB2-L from NEC Electronics, featuring a standby power consumption of just 0.65 µA while the watchdog timer is operating, now broaden Gleichmann Sunrise product range.

The MCUs have a wide range of peripheral units such as a PWM timer (with dead-time) for motors and solenoid actuators, comparators for instant control of timers and an internal 4 MHz oscillator. Thanks to the integrated LIN interface and up to 16 KB of flash, the devices can be used in LIN networks. Furthermore, the flash memory supports EEPROM emulation. The data stored is therefore retained even after loss of the supply voltage.

Based on the current 78K0 architecture and designed for an operating temperature up to +125 °C, the MCUs are ideal as watchdog for a main controller or as electronic control such as full-bridge control of high-density discharge lamps, as full/half-bridge control of motor switching, as switching control of solenoid drivers or for the pulse-modulation for dimming of LEDs. Developers, who already have experience with 78K0/Kx2 and/or 78K0/Fx2 based solutions, benefit from the downward compatibility of the 78K0/Fx2-L products.

Datasheets and samples of the new 8-bit body control MCUs are available now. Mass production is scheduled to begin in August 2010.
